EDGAR M. SMITH, OF NEW YORK, N. Y., ASSIGNOR TO MITCHELL, VANCE & (30.,OF SAME PLACE.

CHANDELI ER.

SPECIFICATION forming part of Letters Patent No. 235,036, dated.November 30, ,1880, Application filed October 19, 1880. (No model.)

To all whom it may concern:

Be it known that I, EDGAR M. SMITH, of the city, county, and State ofNew York, have invented certain Improvements in Chandeliers; and I dohereby declare that the followin g is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, forming part of this specification.

My invention relates to that class of chandeliers commonly known asextension-chandeliers and it has for its object the supply of a cheap,efficient, and effective means for the raising, and lowering, andholding at any desired elevation such chandeliers.

Figure 1 is a side view of a portion of a chandelier to which myinvention is applied. Figs. 2, 3, and 4 represent details thereof,partly in section and partly in side elevation.

E is a rod extending downward from the main support of thechandelier.This rod is rectangular in its cross-section, or it may be of any formwhich will prevent the hereinafter-named sleeve from turning on itslongi- 2 5 tudinal axis. Upon it is fitted the sleeve S, having at thetop a collar, 8, the opening in which corresponds to the shape of therod. This prevents the sleeve from turning horizontally upon said rod E.In the side of the rod E are formed at shortintervals recesses h.

To the top of the sleeve S is permanently fixed a collar, 0. This collarhas a lateral extension, to which is pivoted a hook or stop, 0. In aguide, g, attached to the side of the 5 sleeve, is fitted abent slidingrod, B. The

, upper end of this rod is attached to a slide, N H, in which is formedan inclined slot, h, in which plays a pin, a, which projects from theside of the book (3.

In the cylindrical guide 9 is fitted a coiled spring, It, which actsagainst a collar, 7', at-

tached to the lower partot' the rod B to force the same downward.

The operation is as follows Whenever the lamps are taken off thechandelier for filling 4 5 or cleaning, the counterpoising-weights (orsprings, as the case may be) tend to raise the chandelier. When thelamps are in position their total weight slightly overbalances theweight of the counterpoises and. the chande- 5o lier tends to descend.Either one or the other tendency is opposed by the engagement of thehook or stop 0 with the recesses h in the rod E. The normal position ofsaid hook or stop is such as to compel such engagement, the 5 5 coiledspring R pulling the rod B downward. To release the hook from suchengagement, while the hand grasps the lower part or boss of thechandelier, a slight pressure of the thumb is exerted on the thumb-piecea, and then the whole may be raised or lowered to any desired position,in which it will be retained by the engagement of-the hook or stop 0 inone or other of the recesses h.

Having thus fully described my improve- 6 5 ments, what I claim as myinvention, and desire to secure by Letters Patent, is as follows:

The combination of the rod E, having recesses h, sleeve S, fitted toslide on the rod E, hook or stop 0, pivoted to the sleeve S, and havingthe'projection a, slide N H, fitted to slide on the upper part of thesleeve, and having the slot h, rod B, attached to the slide N H, andhaving the collar 7', guide g, and spring R, substantially as and forthe purpose speci- 7 5 fied.
